Airtac PB Pen-type Cylinder PB12X80SR
The AirTAC Airtac PB Pen-type Cylinder PB12X80SR is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 80mm stroke. Its slim round barrel and back cover are stainless steel, the M5×0.8 ports keep plumbing compact, and the fast, low-friction piston suits high-cycle small-part handling.

About the Airtac PB Pen-type Cylinder PB12X80SR
The AirTAC PB12X80SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a 12 mm bore and an 80 mm stroke, generating 56.5 N of push force and 46.7 N of pull force at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide durability in damp or mildly corrosive environments while keeping end-of-arm tooling light.
This configuration includes an R axial air inlet for in-line plumbing and an integrated S magnet for position sensing. Air connects via an M5x0.8 port, and the Ø5 mm rod utilizes an M10x1.0 end thread for secure load coupling. Because the rod is only 5 mm thick, it is built for coaxial thrust rather than off-axis loads, so adding an external guide over this 80 mm stroke prevents side-load wear.

| Stroke | 80 mm |
| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |

Specifications follow the official AirTAC PB pen-size datasheet. Piston rod and barrel are stainless steel. Confirm bore, stroke and back-cover option against the product label before installation.
Theoretical Output Force (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 56.5 N | 46.7 N |
| 0.7 MPa (max) | 79.1 N | 65.4 N |
Values are taken from the AirTAC PB thrust table. Because pull acts on the rod-side annular area, pull force is always lower than push. Actual usable force is reduced by friction — size with a margin.

Where the Airtac PB Pen-type Cylinder PB12X80SR Is Used
PCB Depaneling Router
Pushes a light carrier fixture against a fixed fence on an automated routing machine, utilizing the 56.5 N extend force to hold the board steady during milling.
Blister Pack Sealing
Cycles an 80 mm stroke to lower a thin heat-seal head onto blister card stock, taking advantage of the fast 50-800 mm/s speed range for high-throughput packaging.
Lab Sample Dispensing
Actuates a small volumetric valve for reagent dosing, where the SUS304 build resists humidity and the S magnet triggers an electronic switch to confirm dose completion.
Is the Airtac PB Pen-type Cylinder PB12X80SR the Right Cylinder?
When sizing this actuator, stepping down to the Ø10 bore yields 39.3 N of push at 0.5 MPa, while stepping up to the Ø16 bore provides 100.5 N, letting you match the exact force requirement.
Confirm your ordering essentials: 12 mm bore, 80 mm stroke, M5x0.8 port, S magnet, and R axial inlet. Note that a plain PB body does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed TPU bumper only decelerates it near the stroke end. If your process requires a fail-safe hold, specify an external rod lock or mechanical stop.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Slim pen body vs. a standard round cylinder
- ✓ Back cover: CB / U / R inlet direction
- ✓ Magnet (S) for sensors?
- ✓ Mounting: LB / FA / CJ or front thread
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.7 MPa operating pressure.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
- check Fit dust caps to ports during long-term storage.
- check Installation by qualified personnel per AirTAC docs.
Airtac PB Pen-type Cylinder PB12X80SR FAQ
At 0.5 MPa, the push (extend) force is 56.5 N and the pull (retract) force is 46.7 N. At the maximum operating pressure of 0.7 MPa, the push force is 79.1 N and the pull force is 65.4 N. The operating pressure range is 0.15-0.7 MPa, with a speed range of 50-800 mm/s.
End cushioning is provided by a fixed TPU bumper at each end and cannot be field-adjusted; for high-speed or heavy tooling mass, meter-out the exhaust or add an external shock absorber. The S code indicates a built-in piston magnet that works with AirTAC reed or electronic switches for position detection.
